Technicals for Summer Asset Management Internship

Hi everyone. I’m entering my second year at a commerce undergraduate program in Canada. My goal for next summer is to obtain an asset management internship, preferably at a big 5 asset management branch. Currently i’m working as a trading intern at an asset management firm since I have some close connections at the firm and was able to get my resume passed on internally. I was just wondering how I should prepare in these next couple months to maximize my chance of landing an internship as an analyst. For those in the industry or also pursuing an internship, what technicals should I work on and how should I prepare? Any help is greatly appreciated, thanks!
